Using Gods, Demigods, and Heroes By Kuntz & Ward for original Dungeons & Dragons with Barrows and Borderlands Rpg

 Integrating the monumental 1980 supplement Gods, Demigods, and Heroes (Supplement IV) with Barrows & Borderlands (a modern "Old School Essentials" style hack) creates a high-powered, mythic campaign atmosphere.

While Original D&D (OD&D) provides the raw stats for deities, Barrows & Borderlands provides the grit and procedural exploration. Here is how to blend these two worlds effectively.

1. The Role of Deities in Play

In Supplement IV, gods weren't just background lore; they were NPCs with Hit Points (often 300+), Armor Classes (frequently -10), and literal presence.

• The Power Scale: In Barrows & Borderlands, where a 1st-level Thief is incredibly fragile, a deity appearing is a "world-ending" event. Use them as Patrons or Cataclysms rather than combat encounters.

• Alignment Matters: Supplement IV categorizes gods by pantheon (Greek, Norse, Egyptian, etc.). Use these to define the "Borderlands." Perhaps the Lawful Norse gods hold the walled cities, while the Chaotic Egyptian gods rule the desert wastes.

2. Converting Stats to B&B

Since Barrows & Borderlands uses an OSR-adjacent chassis, the conversion is straightforward but requires some "squishing" to maintain the B&B lethality.

Attribute	Supplement IV Standard	B&B Implementation
Armor Class	Often negative (e.g., -2 or -10)	Convert to Ascending AC. An AC of -2 becomes 22; -10 becomes 30.
Magic Resistance	Percentage based (e.g., 75%)	Use as a flat "Saving Throw" bonus or a "Magic Immunity" trait.
Hit Dice/Points	Fixed HP (300+)	Keep the high HP. In B&B, this makes them virtually unkillable by mundane means.
Move	High inches (e.g., 24")	Triple the standard human movement rate.

3. Heroes and Demigods as PC Benchmarks

Supplement IV introduces legendary figures like Hercules or Beowulf. In a Barrows & Borderlands campaign, these serve as the "Level 20+" endgame.

• Divine Spark: If a player reaches the level cap in B&B, allow them to quest for a "Spark" to become a Demigod. Use the Supplement IV stats as their new "Base Form."

• The Artifacts: Supplement IV is famous for items like Mjolnir or The Iron Crown. In the Borderlands, these shouldn't be found in a random chest. They should be the "Megadungeon" rewards at the bottom of the deepest Barrows.

4. The "Borderlands" Theology

To make these gods feel authentic to the Barrows & Borderlands aesthetic, tie them to the landscape:

The Barrows (The Dead Gods)

Use the Egyptian or Sumerian pantheons here. These gods are often depicted as being obsessed with the afterlife. The "Barrows" aren't just graves for kings; they are prisons for demigods who refused to die.

The Borderlands (The Active Gods)

Use the Norse or Greek pantheons. These are "Wilder" gods.

• Odin might appear as a hooded traveler at a campfire in the Borderlands.

• Pan might be the source of the chaotic "Fey" energy that makes the woods so dangerous for B&B adventurers.

5. Mechanical Integration: Clerics & Paladins

In B&B, Clerics usually choose a generic "Light" or "Dark" path. Supplement IV allows you to specialize:

1. Grant Specific Boons: A Cleric of Thor might gain +1 to damage with hammers (as per his Supplement IV description) but lose the ability to use "Command" spells.

2. Omens: Use the "Divine Intervention" percentages from Supplement IV. If a player performs a truly heroic feat, roll their Alignment % to see if a god notices.

A Note on Power Creep: Supplement IV is notoriously "overpowered" for standard OD&D. If you give a B&B player a "Hero" stat-line (18/00 Strength, etc.), they will trivialize standard monsters. Reserve these stats for temporary "Avatar" states or the literal end of a 5-year campaign.
